snaps lost connections during 22.04 upgrade

[Alfred E. Neumayer]

Upgrading to yesterdays state of 22.04 (from 20.04) led to problems during upgrade, and lost all snap connections.

(To be fair, the release upgrade itself had issues already, that might need an additional bug report, but at least no custom PPAs and just relying on Snaps for work).

Almost none of the applications would start anymore because they lacked permission to the wayland socket and other crucial things.
Reconnecting them solved the individual issues (and gave me a chance to rethink the level of security on a laptop),
but the upgrade process should still handle that properly, and I wouldn't know where to start looking myself.

This is no April Fools joke.
If you insist on an April Fools joke:
Check your Ubuntu Touch devices on devel 2022-04-01 and help us test the camera and screenshots. ;)

Hi Alfred,

Any chance to have journal log (journalctl -u snapd) from the time of upgrade?

Thanks

Status changed to 'Confirmed' because the bug affects multiple users.

Hi Pawel,

this is my log from todays upgrade (focal->jammy):

This may be because of https://launchpad.net/bugs/1967517 ?

@n.buechner no, that's a different problem, most likely:
https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1961898 although in your case it hit a 25s and still did not get a response from systemd.
